What is the best 02 housing / dump pipe for a 2005 Evolution Turbo with the 10:5 hotside?

I see many different makes that all claim they are Evo Specific, but which one would be "the best"?

Looking for compatibility without modification and, of course, overall hp/torque increase, no matter how small the #'s may be....

Thank you O0

best WORKS 02 housing...
i rather spend abit more money and have a cast piece (same as oem) then an aluminum that eventually with time it will crack, and it doesnt have the stock mounting points for support, unlike the WORKS 02

website for "works"? Is it even worth changing the stock one out?

Im trying to also find a downpipe, so far Ive found downpipes all 3" dia with or without a flex pipe, whats the diff? :?

Someone makes an aluminum one? That sounds like trouble. Or did you get into the "everything tubular is aluminum" mindset? That happens to me.

Helix website? Im sure you could help with my install once I get one :grin:

The helix o2 housing fits the 05 evo turbo no problem right? Even though hotside is larger on that turbo??

Works is out of stock, and nearly $500...god damn gina, might as well send my 02 to bushcur and have them port and coat it for half that since its probably minimal gains anyways then it would fit to most DP's? Or am I just :idiot2:

the Helix have een on my car for about 6 thousand miles of driving it like it's stolen and still holding just fine. For the amount of Work o2 housing i rather spend on stuff that have real gains. just my $0.02 cents

have you even track the car yet ?
i know others have with the same piece but i rather spend 125.00 additional and have all the mounting and bracket points, then to take short cuts..
you can't buy much for an additional 125.00-150.00 except a track day and some 100 octane... but we all know that most of the evo community doesn't need to track their evo in order to have fun :roll:

not the same, you are limited to the amount of material you ca remove from the stock piece... have you even seen the pics from the OEM 02 vs WORKS ... you will be suprise ..
theres a reason why they dont have it in stock anymore and other peeps are waiting for it...
its well worth it IMO if you plan to stay with the stock turbo or plan to look into upgrades like the TME, WR, IX turbo, 20g or 21g ...
1 more thing, i believe the WORKS 02 housing works in combination with the WORKS 76mm DP since it was design for it. all i can say is perfect (OEM) fit O0

The works unit is certainly high quality. It's hard to beat the durability of a cast part. It will flow much better then stock, and there you go....

But speaking of flow. You really can't beat the characteristics of a divorced system. It eliminates the turbulance that OEM and the works caste cannot. Plus it weighs about more then 10-15lbs less. Will it hold up under extreme heat? That's a good question. Generally tubular anythings don't unless they're chryo treated.

If you are a daily driver (light to light racer) I would recomend the Helix.
If you are a die hard track enthusiast, you would be safter going with the works.

If you put them both on the dyno, I doubt if you'd see a +/- WHP difference greater then 2.

Well worth it? Who says? I haven't seen a dyno chart yet for the WORK 02 housing. Does it increase spool-up? change the torque curve? Hold HP more up top? Make more power or torque? Who knows?

Someone dyno a car with the only change being the WORKS $$$$ 02 housing and lets see. I know WORKS never dyno-validates any of their parts.

O2 housings dont do jack. If I had access to EvoM i'd pull up some of the many before and after threads relating to O2 housings.

it did improve spool. havent had the car dyno period, so after i had the car tune, all i did was change the 02 housing.. but i dont have a base run to begin with...
well worth it, since if you are trying to gain the most hp possible out of the stock turbo or any of the modify stock units i mention.. an 02 housing would be something to consider... (whether is the WORKS or after market parts)
well worth it, you and i both know very well how much stress can be added at a track event, and if there is a weaknest on a part, it will be found... i decided to go with the WORKS for several reasons
1. same as OEM (stock mounting points) using the 02 bracket for support, unlike the helix or any SS 02 housing.
2. cast and not SS.. which at the end it will hold or prevent cracking in the future (reason why the stock unit is cast.
3. it improved spool
4. WORKS quality it's just amazing! i'm very happy with all the products i have purchase from them.. having OEM fitment quality.
spending 150.00 more and being able to obtain a cast piece, well worth it IMO..

You could have saved $50 and just bought the ebay 02 housing, it's the exact same thing made by the same company that supplies helix and megan racing.

I have one for sale if anyone is interested. Brand new in box. :D

Just as a side note, std O2 outlet is 55mm and Works oulet is 76.

believe the tommie O2 housing has a engine mount/ support but it costs like $600

I'm getting the WORKS housing as the number 1 rule of turbo's: No exhaust after the turbine is the best, everything else is a compramise...

Please dyno the car so we know how much it "improved spool". I haven't had a problem making good hp out of the stock 02 housing. I'll spend $400+ on something else.

well i was going to buy an 02 housing regarless...so whether spending 150.00 (for the ebay 02 housing which my friend had and decided to take off... ) in his own words "junk"
i rather spend abit more and not deal with the headaches...
but i will dyno the car , but keep in mind that it will have other additional things
like BJs stage 5++ head
cams (maybe 280/280) or staying with a 272/280 set up (havent decided )
and a dr.gray stage 1+

Ok so we still won't know what the WORKS 02 added then. Will have no idea from all those mods being added at the same time.

i believe some one is making one that will retain stock manifold, stock DP and stock 02 housing... like a 3052 which would be more then enough for me... till i get an AMS stroker kit or a 2.4l bottom end 8)

1. what does having social skills have anything to do with this thread
2. do you even know if i get out or not... ?? maybe abit more then you ohhh wait a minute... if i lack on social skills, i can imagine how much you do as well, since your best friends are a camera, a clay bar and soapy water.. since all you do is wash your damn car all the time.. can we say at least 4 times a week.. at least...
3. the reason i mention the track (you wab!) is because you push the parts to a certain level, and having something that will last longer then a SS material is very important IMO... like cast (especially something near the turbo area...) besides this has been argue many times in the past.. don't plan to start something like this all over again...

No, they don't. That would require, again, for someone to recast the hotside with the same bolt pattern and port design as the stock manifold and 02 housing.

Don't you think that would be much bigger news as that what EVERYONE is waiting for?

The forum-restricted vendor you speak of mearly has a cast adapter piece that goes inbetween the turbo and the stock exhaust manifold. It uses its own DP that deletes the 02 housing altogether:
